SPECIFICATION forming part of Letters Patent No. 764,387, dated July 5, 1904.

Application filed October 3, 1903- To all whom it may concern:

Be it known that LRUssELL E. SrIvEY, a citizen of the United States, residing at Oneida, in the county of Knox and State of Illinois, have invented new and useful Improvements in Calculating-Machines, of which the following is a specification.

My invention has relation to improvements in machines for computing, ascertaining, and indicating the cost of goods sold, whether disposed of by lineal measurement or by numbers; and the object is to provide a computing machine or apparatus which is simple in construction, effective in operation, and aecurate in the ascertainment of the results and determinations of values and amounts.

WVith these objects in view the invention embodies a graduated cylinder, means to retate the cylinder, graduated racks surroundingthe cylinder, and stops to engage the racks at determined points and to stop the cylinder at such points, all as will be hereinafter fully specified and the asserted novelty particularly pointed out and distinctly claimed.

My invention is fully and clearly illustrated in the annexed drawings, to be taken as a part of this specification and reference being had thereto.

Figure 1 is a top plan view of a portion of a counter or table to which my computing device is operatively applied, showing the indicating-plate positioned in the counter and the initial line of indications on the cylinder as resting between the bottom flanges of the indicatingplate, also showing the fingerpieces of the operating-levers and certain of the graduated rack-teeth. Fig. 2 is a vertical cross-section taken on line 2 2 of Fig. 1, showing the actuating-spring, the indicatingplate, and the holding-lever or key as in engagement with the stop-lug on the cylinder. Fig. 3 is a vertical cross-section taken on the line 3 3 of Fig. 1, showing in side view the first circular rack and the pawl-lever or key for engaging and stopping rotation of the cylinder. Fig. 4. is a vertical cross-section taken on the line 4 4 of Fig. 1, showing the toothed rack for holding the cylinder at the point to which it may be turned and in- Serial No. 175,669. (No model.)

dicating in black the circular rack constituting the second of the number or series and also showing the holding pawl or lever and the pawl and lever for stopping the cylinder at the distance of each tooth at a time. Fig. 5 is a vertical cross-section taken on the line 5 5 of Fig. 1, showing the teeth of the third circular rack, the pawl-lever to stop the rotation of the cylinder, and also one of the springs for holding the lever-bar or bail common to all the stop levers or pawls. Fig. 6 is a ver tical cross-section taken on the line 6 6 of Fig. 1, showing the teeth of the fourth circular rack of the series and the pawl-lever for stopping the rotation of the cylinder at the distance of each tooth. Fig. 7 is a longitudinal vertical section on the line 7 7 of Fig. 1, showing the cylinder-shaft with actuatingspring and gearing and a crankhandle for winding up the spring. Fig. 8 is a plan \lOW of the graduated cylinder. Fig. 9 is a bottom plan view of the counter or table, showing the under side of the indicating-plate and the arrangement of the several pawl or stop levers and the spring-held bar or bailcommon to all the levers. Fig. 10 is a detail perspective of one of the jointed pawl-levers.

In the drawings the same parts appearing in the several illustrations are designated by like reference notations.

A designates a cylinder made of sheet metal and of such length and diameter as will adapt it to be supplied with the indications of measurements or numerical numbers of articles and the product of their cost at any stated price. This cylinder is provided with suitable end pieces or heads 1 2, having inwardlyextended annular flanges, as shown in Fig. 7 of the drawings, fitting firmly in the ends, the headsbeing made with central hubs 3, mounted fast on a shaft 4, projected lengthwise through the cylinder. On one end of the shaft 4: is mounted a pinion 5, which is engaged by a spur-wheel 6 on a shaft 7, on which is mounted a coiled spring 8, which constitutes the means for imparting rotation to the cylinder. On,the one end of the shaft 1 is a crank-handle 9, by which the motor-spring may be wound up when required.

1O designates a top piece of a table or counter having secured to its under side hangers 11 12, provided with bearings wherein the shaft 4 of the cylinder is journaled. The hanger 12 is provided with a bracket 13, in which the shaft 7 of the spur-wheel 6 and the spring is journaled, substantially as seen in thedra'wings. The cylinder A' is divided on itsface by longitudinal lines 14, arranged at -"detcrmined spaces apart, according to the size of the cylinder and the number of computations to be recorded and ascertained. These longitudinal lines 14: are intersected by parallel circumferential lines 15, thus dividing the surface of the cylinder into rectangular spaces, as seen in Fig. 8 of the drawings, wherein an initial line of squares, as 16, are indited in numerical progression or sequence from left to right, the cost or price of yards or articles to be sold, as instanced in the drawings, where the price starts at four cents and,

including fractions, runs to thirty-two cents. In the first annular column at the left of the cylinder are stated the measurements of articles or goods sold, and commencing in each space next the price-indicating line and con' tinuing in each annular column around the cylinder. are set down opposite the measurements the ascertained total costs for such measurements or for so many things. Because a single instance demonstrates the whole the cylinder is not shown as supplied with the complete products; but it is apparent that in practice the indications will be made complete and the prices computed and accuratelyplaced.

In the counter or table top is made an opening extending the length of the cylinder, and in this opening is arranged an indicator 17, consisting of a box-like construction having flanges around its upper portion which rest on coincident flanges made on the edges of the counter surrounding the opening and formed with turned-in flanges 18 with a longitudinal slot between them, and on the faces of the flanges 18 are placed the same nu- Ineral designations as are indited on the initial price-line of the cylinder, as shown in Fig. 1 of the'drawings. This arrangement of the prescribed initial price indications permits ready visual observation of the price from either direction of the sight and ascertainment of the primary position of the initial price-line and the computation of the whole cost of the sale. In the indicator plate or box are transverse slots or openings, as seen in Figs. 1 and 9, to provide accommodation for the passage of the ratchet-teeth mounted on the cylinder. The indicator is covered by a pane of glass 19, held in place by suitable cleats or the usual cementing material 20. On the cylinder is a stop-lug 21, which lodges against the end of a spring-pressed lever 22, fulcrumed to the under face of the counter and having its outer end extended vertically through an aperture in the counter and provided with a finger-tip on which is a suitable designation. At a selected point in the cylinder is positioned a ratchet-ring 23, the teeth of which are in alinement'with the spaces between the longitudinal lines on the'cylinder, so that by the action of the associated lever actin g at this point the cylinder will be stopped in rotation at each tooth. A second ratclietring 24 is mounted on the cylinder, having teeth twice the length of the ratchet-ring 23, so that under the action of the lever engaging with this ratchet-ring the cylinder will rotate the distance of two spaces of the lines and then be stopped. A third ratchet-ring 25 is mounted on the cylinder the teeth of which are three times larger than the teeth of the ring 23, and the cylinder can therefore rotate by the action of the lever at this point the distance of three teeth of the ring 23 and then be stopped, and anotherratchet-ring 26, the last of the number and the teethof which are four times the length of the teeth of the ring 23, and the cylinder will rotate the distance covering four spaces of the lines. Associated with each ratchet-ring is a pawl-lever for stopping the rotationof the cylinder at the required point. These pawl-levers are of like construction and all stand normally out of engagement with the ratchetrings, as indicated in the drawings. Referring to the several illustrations of these pawl-levers,27 designates the arm or bar, which constitutes the pawl, which is pivotally supported in a depending support 28, secured'to the under face of the counter, the outer end of the part 27 being reduced and arranged between the forked end of the lever 29, a pivot-pin 30 being projected spring 33 is placed between the joint and the under face of the counter, substantially as shown. Pivotally supported to the counter is a bail 34, common to all the pawl-levers and pressed upward against them by springs 35.

This bail bears against all the levers 29, as

seen in the drawings, and is swung downward on ilts journals when any one of the levers is use On the cylinder is mounted a ratchet-ring 36, constituting the member or element which holds the cylinder at any point to which it may be turned. The teeth of the ring 36 are identical in size with those on the first ratchetring 23, so that a movement of the cylinder may traverse one tooth or four teeth of this ring, according as to which lever is used. 37 designates a lever-which engages the teeth of the ring 36 and is fulcrumed in a hanger 38, to which a spring 39 is secured, which bears upon the inner arm of the lever with sufficient force to snap its nose into the teeth in succession or whenever pressure on its outer arm is removed. The lever 37 isdisengaged from the teeth of the ring 36 by the downward movement of the bail 34, which rests on the lever, as seen in Fig. 4 of the drawings. The

several finger-pieces of the levers are properly designated-that of the starting-lever as a, the one-fourth yard 6, the one-half yard 0,

the three-fourths yard (Z, and the full. yard 6- the initial or base price-line in alinement with the slot between the flanges of the indicatingplate and the lug 21 lodged against the nose of the lever 22, as seen in Figs. 1 and 2 of the drawings. The spring is wound up and the apparatus is ready to be utilized. Now suppose a sale is made of one yard and a quarter at four cents per yard. The finger-piece a is depressed to release the cylinder. Then the one-yard finger-piece is depressed once, which movement releases the holding-lever 37 from its engagement with the ratchet-ring 36, and the cylinder is rotated the length of one tooth of the ratchet-ring 26. Then the fingerpiece I) is depressed and the holding-lever, which has returned into engagement with the ratchet-ring 36, is again released and the cylinder rotates the distance of one tooth of the ratchet-ring 23, which rotations have carried the cost of the sale into view between the figures 4 on the flanges of the indicator and the measurement (one and one-fourth yards) between the Nos. at the end of the line. Again, suppose a sale is made of one yard and three-fourths at sixteen cents a yard. The lever 22 is first released from the lug 21, then the one-yard finger-piece e is depressed, which permits the cylinder to rotate the length of one tooth of the ratchet-ring 26, and then the finger-piece (Z is depressed and the cylinder rotates the distance of one tooth of the ring 25, which brings the figures 28, the cost, between the figures 16 on the flanges of the indicator, and the measure (one and threefourths) between the Nos. at the end of the line.

- It is apparent that the cylinder may be lengthened and the divisional sections of the cylinder be increased, so. as to employ additional ratchet-rings having teeth proportionately increased in length.

Having described my invention, what I claim is 1. In a computing-machine, a rotary computing-cylinder, having annular progressive computations thereon and an annular progress ive number-line all commencing on an initial base-line, means to permit the determined rotation of thelcylinder for difiercnt distances arranged at stated intervals thereon, means on the body of the cylinder to stop the latter at any determined pointin rotation, and means to hold the cylinder at a determined point against rotation.

2. In a computing-machine, a rotative cylinder having annular progressive price coniputations thereon, and an annular progressive number-line, means to hold the cylinder at a determined point against rotation, a series of ratchet-rings on the cylinder having teeth increasing in length in determined progression throughout the series from the first to the last ring, pawl-levers to engage the teeth of the respective rings and stop the cylinder at the required points, a cylinder-holding ratchetring on the cylinder having teeth the same length as those of the first ring of the series, and a lever to engage the holding-ring.

3. In a computing-machine, a rotatory cylinder having annular progressive price computations thereon and an annular progressive number-line, means to hold the cylinder at a determined initial point against rotation, a

series of ratchet-rings on the cylinder having teeth increasing in length in determined progression throughout the series from the first to the last ring, pawl-levers to engage the teeth of the respective rings and stop the cylinder at the required points, said pawl-levers standing normally out of engagement with the ratchet-rings and any one of the levers acting independently of the others, a cylinder-holding ratchet-ring on the cylinder having teeth the same length as those of the first ring of the series, a lever to engage the holding-ring, and a bail common to all the levers to release the holding-lever.
